Virtual Image Display Speaker Layout for Thin Temple Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted image display devices with speakers mounted near the ear require complex wiring and may increase temple thickness, limiting mounting characteristics and speaker arrangement options.
Innovation Solution
A virtual image display device with speakers mounted on a mounting member, featuring an opening portion for sound output at the coupling between the mounting member and temple member, and utilizing hollow temple members to guide sound to the ear, eliminating the need for complex wiring and reducing temple thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the speaker is mounted on the temple near the ear, then sound transmission to the ear is achieved, but wiring becomes complex and temple thickness increases
Solution Approach 1:
The speaker is extracted from the temple structure and mounted on the mounting member instead. This separates the sound generation function from the temple, eliminating the need for complex wiring through the temple and allowing the temple to maintain its original thickness and structure.
Solution Approach 2:
The mounting member acts as an intermediary structure that houses the speaker and provides a direct sound transmission path to the ear through the coupling portion, bypassing the need for complex wiring through the temple while maintaining effective sound delivery.
2Reliability
If the speaker is mounted on the temple near the ear, then sound transmission to the ear is achieved, but temple thickness increases affecting mounting characteristics
Solution Approach 1:
The speaker is extracted from the temple structure and mounted on the mounting member instead. This separates the sound generation function from the temple, allowing the temple to maintain its original thickness and structure without accommodation for the speaker.
Solution Approach 2:
The speaker is positioned in a different spatial location (on the mounting member rather than on the temple), changing the dimensional arrangement of components. This allows sound transmission without increasing temple thickness by utilizing the mounting member as a separate platform.
3Reliability
If the speaker is mounted on the temple near the ear, then sound transmission to the ear is achieved, but speaker arrangement options are limited
Solution Approach 1:
The speaker is extracted from the temple structure and mounted on the mounting member instead. This separates the sound generation function from the temple, providing flexible arrangement options for the speaker on the mounting member without being constrained by temple geometry or thickness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for efficient sound transmission without increasing temple thickness, maintaining device compactness, and providing flexible speaker arrangement options.
Implementation Method 1
a speaker (SKb) mounted on the mounting member (MT), and the speaker (SKb) has an opening portion (OP) for sound output at a coupling portion between the mounting member (MT) and the temple member (100D)

AI summary
A virtual image display device includes a display element, a mounting member that fixes the display element, a temple member that is coupled to the mounting member, and a speaker that is mounted on the mounting member. The speaker has an opening portion for sound output at a coupling portion between the mounting member and the temple member.
